The proposed concept has been firstly verified by the laboratory-scale experiments in which benzene, toluene and naphthalene were chosen as tar model compounds. It has been observed at about 500 °C, GHSV > 25 000 h–1 and H2O/C = 18 mol mol–1 that conversions of all tar model compounds higher than 95 % can be gained. Secondly, experiments with real producer gas have been performed. A side stream of hot raw producer gas was dedusted in the first reactor at temperatures 550–600 °C. Gas was exposed to the chosen-nickel based catalyst at about 500 °C, GHSV = 3360–6000 h–1 and H2O/C = 5–6 mol mol–1. It has been found, that hydrocarbons higher than methane including tar species were decomposed into H2 and CO2. Tar species were effectively decomposed from more than 3 g m–3 to less than 17 mg m–3 which corresponds to conversions higher than 99 %.
